Design a light-mode web interface screen: crisp institutional liquidity rendered in luminous royal blue, layered white elevations, and calibrated fintech typography.
LAYOUT
The page follows an asymmetric dashboard grid anchored by a persistent 240px vertical sidebar on the left. The remaining viewport is divided into a dominant 68% center workspace and a 32% right analytical utility column. The center column stacks vertically: a 240px high dark hero banner, a four-tile horizontal KPI row, an expansive historical line chart, and a bottom quick-actions dock. The right sidebar balances this with a donut allocation breakdown stacked neatly atop a five-row market gainers table.
PALETTE (use these exact hex values)
- #F5F7FC — Canvas Background: structural backdrop for the overall interface beneath all panels and navigation
- #FFFFFF — Card Surface: elevated card surfaces, active sidebar controls, and data module containers
- linear-gradient(135deg, #070E28 0%, #0F2454 100%) — Hero Midnight Gradient: featured promotional banner background anchoring the primary top-left layout
- #0062FF — Electric Blue: primary call-to-action buttons, active navigation indicators, and primary chart stroke
- #EDF4FF — Active Surface Tint: background for active sidebar nav item and secondary interactive pill buttons
- #10B981 — Gainer Emerald: positive 24-hour delta indicators, upward trajectory arrows, and yield figures
- #0F172A — Graphite Primary: high-emphasis headings, key balance figures, asset symbols, and data values
- #64748B — Muted Slate: subordinate labels, table column headers, timestamps, and breadcrumbs
- #E2E8F0 — Subtle Outline: hairline borders separating panels, inputs, cards, and list rows
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans, SF Pro Display, Roboto), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 18px subheading, 24px heading, 30px display. Tracking -0.02em at display, 0 at body. The typography is rigorously technical, modern, and trustworthy, evoking elite fintech platforms like Stripe and Coinbase. Inter provides optimal legibility at micro-scales (11px-12px) for asset tickers, while its heavier weights (600-700) deliver punchy display values without compromising horizontal density. If Inter is unavailable, Plus Jakarta Sans or SF Pro Display offer identical structural clarity.
GEOMETRY & SPACING
Corner radii — cards 16px, links 6px, inputs 12px, buttons 10px. Spacing on a 4px unit, 16px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is communicated primarily through structural surface contrast rather than pronounced drop shadows. Pristine white `#FFFFFF` cards sit on a cool `#F5F7FC` tinted canvas with hairline `#E2E8F0` borders and an ultra-soft, diffused ambient shadow (0px 2px 8px rgba(0, 15, 50, 0.04)). The midnight hero card provides dramatic tonal depth through high luminosity contrast rather than physical layering.
IMAGERY
Visual imagery is concentrated within the promotional banner, leveraging hyper-clean 3D renders of a matte smartphone and glossy, dimensionally lit crypto coins (Bitcoin, Ethereum, Solana). Renderings feature soft rim-lighting and ambient blue glows. Stock photography of people, flat line clip art, or skeuomorphic textures are strictly excluded.
SIGNATURE DETAIL — the thing that makes this design itself
The singular visual identity stems from the sharp juxtaposition of the midnight navy 3D hero card (`#070E28`) sitting immediately above clean, white light-mode analytical modules (`#FFFFFF`) with vivid electric blue (`#0062FF`) line work. It delivers the excitement of Web3 marketing alongside the disciplined utility of an institutional banking platform. Misusing it by converting other cards to dark mode ruins the focal hierarchy.
MUST
- Use pure white `#FFFFFF` for data card surfaces against the `#F5F7FC` background.
- Restrict the dark midnight tone `#070E28` solely to the marketing hero banner.
- Enforce 16px border-radius consistently on primary analytical cards and module containers.
- Display all positive market percentages with the green token `#10B981` and leading upward arrow.
AVOID
- Do not render primary cards in dark mode or saturated colors outside the hero.
- Never use red or disruptive warning colors for ordinary, non-critical interface alerts.
- Do not drop card corner radius below 12px or exceed 20px on standard widgets.
- Avoid decorative serif typefaces or non-standard weights for financial tables.
